IMPRVEMENT IN THRESHINGMACHINES.

vThe Schedule referred to in these Lettera Patent and making part of the same.

To all whom it may concer-n Beit known that we, GEORGE M. RHoADns, of Hamilton, in the county of Madison, and State of New York, and GEORGE B. HAMLIN,ofWiilimantic, inthe. county of Windham, and State of Connecticut, have invented a. new and useful Improvement in 'lln'eshing-Machines;

and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable more efficient in use and less liable to get ont of order' or to be broken than the machines constructed in the ordinary manner; and

It consists in the construction and combination of various parts of the machine as hereinafter more fully described.

A represents the casing or frame-work of the machine.

B is the threshing cylinder, the shaft b1 of which revotves in slot-s in the iiame A, or in slotted bearings attached to said frame.

The cylinder Bis formed by attachinga drum or shell, b2, to two wheels'or'disks attached to the shafts b1, said wheels or disks heilig made heavy, so as to act as Ily-A wheels.

C are teeth which pass in through slots in the drum or shell b2 of the cylinder B, and have cross-heads formed upon their inner ends, by means of which the inner ends of the said teeth are pivoted to lugs formed upon or attached to the inner surface of said drum or shell b.

D is the concave, which corresponds in curve to the curve of the drum of the cylinder B.

E are teeth, the upper ends of which project through slots in the concave D, and which are pivoted to lugs formed upon or attached to the lower or convex surface of the concave 1). A

The lower ends of the teeth E are weighted or made heavy, so as to counter-balance their upper ends suiiciently to support any loose heads of grain that may be passing down the concave, but not suliiciently to hold the said heads against the act-ion of the teeth C.

F is the rack by which the straw is guidedas it passes ont of the thresher, and through which the grain falls to the vibrating spout G.

Through a hole in the lower end ofthe spout G the grain falls upon the screens H, which are rigidly connected with the spout G, and which are connected with and agitated from a cam upon the journal ot'. one of the drive wheels by means of a system of connecting rods and levers, hh2 h3.

To one end of the cylinder shaft b are attached the fans of a flan blower, the blast from which is discharged through the pipe I upon the grain as it passes throng the machine.

To the other end of the shaft bl-is attached a friction pulley, J, which works between the faces of the wheels .K and L.

The journals of the wheels K and L revolve i'n bearings iu the frame-work of the machine. The journals of one of the wheels, L, should revolve in slotted bearings, so that it may be held in contact with the friction pulley J by its own weight, or by the tension of the belt M.

The belt M passes around the wheels K a d L, as shown in lig. VI.

The power by which the machine is driven is applied to the projecting end of the journal 0f the wheel L by any of the well-known moans for such purposes.

By this construction and arrangement of the driving gearing there will be no more strain upon the shafts when the machine is working than there is where said machine is running free.

Having thus described our invention,`

We claim as new, and desire to secure by Letters Patentn 1. rlhe combination of pivoted teeth with the drum of the threshing cylinder of a threshing-machine, substantially as herein shown and described and for the lpurpose set forth.

2. The combination of pivoted and weighted teeth with the concave of a threshing-machine, substantially as herein shown and described and for the purpose set forth.

3. An improved driving gearing, formed by the combination ofthe friction-pulley J, attached to the shaftl to be driven, the wheels K and L and belt M with each other, substantially as herein shown and described and for the purpose set forth.

The above specification of our invention signed by us, this 27th day of January, 1869.

GEO. M. RHODES. GEORGE B. HAMLIN.
